I think my only complaint regarding this Manga is that for a story about Eldritch Horrors in Human Form, this all makes far too much sense. Especially with these two new characters, this is basically just the normal "My Girlfriend saves the world from monsters while I tag along and nebulously help with stuff" story with a vaguely Eldritch paint job.
I'm'a still read it, and I'm'a still like it, but I wish it was less comprehensible.
